Re: [RE-wrenches] XW Drop in replacement inverter

[Dave Angelini Offgrid Solar via RE-wrenches]

Hi Chad,

Yes XWpro 6848 is a drop-in  replacement. Exact fit & all connections 
are the same as way back to 2006 when the "grey box" XW 6048 was sold. 
You need a connext insight home or facility device to do the initial 
configuration.


It is a one time need for the insight home device to set the mode for 
offgrid. There are numerous new settings
that will not work with the old SCP he has, but you do not need them for 
a replacement.


You should not need to change firmware either as long as the system was 
working. Most new firmware is for the closed loop support of 10 
different LFP battery systems and new grid features. There is one LFP 
battery Discover AES that all settings are hard written and read by 
connecting one xanbus network cable.

[RE-wrenches] XW Drop in replacement inverter

[Chad Waits via RE-wrenches]

Wrenches,

We have a client that had us construct a solar trailer for them back in
2014-2015 timeframe. The Current XW6048-120/240-60 is cooked and I'm
wondering if the Schneider rep (or you savvy off grid guys) on here could
tell me if the newer XW Pro 6.8kW 120/240 is an exact drop in replacement
for a system including the the old power distribution panel accessories.

Thanks!

Wrenches
I have always used 50 miles per hr as this works well, sure the 3600 rpm
unit runs faster but 2000 hrs is 10 miles and unless you have a prime
mover that's about right. I see many with well over 10,000 hrs. Had one
last week do 1000 hrs in a month.

Re: [RE-wrenches] Sunny Island AC-Coupled system integration with Fortress E-Vault

[Kienan Maxfield via RE-wrenches]

William,

The charge controllers could operate in open loop, while the SMA did close the 
loop. Open loop works really well for charge controllers.

I question if the closed loop communication was really working correctly if the 
SI is reporting 50% SOC when the batteries are reporting 95%… The SI should be 
getting its % info from the batteries…

My thoughts are that the inverter needs to start frequency shifting at a lower 
voltage. If the closed loop communication isn’t working correctly, you could 
try setting a lower absorb and float voltage…

I’ve had bad luck using open loop Lithium with SMA…

If you were to consider switching out the inverters, consider putting in 
Fortress Envy inverters.

Hello
Have any of you been in contact with tech support at Schneider? I haven't 
worked with their equipment in several years. I'm working on repairing another 
contractor's system, and when I tried to call tech support in the middle of the 
day, no one answered the call. I remember several years ago there was a special 
number to press once you were in the Schneider tech support answering system, 
but if you followed the prompts you wouldn't actually get to tech support.

Thanks in advance to anyone who can help,

It’s a very poorly designed system. But it is possible to view the full error

online right now to advise exactly what parameter but it was near the bottom of

How can one read error and/or warning code either via Sunny Portal or port

I can see charts galore on the Portal but I can’t find error or warning logs.

Also, I get alerts via email but they are vague, as in “3xx” or “7xx”.

Apologies if this is a dumb question.

[RE-wrenches] On Gens : 2007 Kohler: Wrenches, can you help with parts or smarts?

[Dana Orzel via RE-wrenches]

REF Hours on Generators:

 

Air cooled 3,600 RPM = 80 Mph

5000 hours x 80mph = 400,000 miles

 

Water cooled at 1,800RPM = 40 MPH

5000 hours x 40mph = 200,000 miles

 

Both are a lot of hours but 400K is till a whole lot of wear & tear.

 

I got to thinking about all the other impacts & considerations:

 

*   Low elevation VS high elevation
*   Light loading vs heavy prolonged loading
*   Air flow & operating temps?
*   Warm up & Cool down cycle VS on & off.
*   Synthetic oil VS dinosaur oil? Synthetic = 4x the life & still
better than dino oil when it was new.
*   Are they exceeding the oil intervals because they are always adding
& adding oil due to consumption?
*   Rodent impact on wiring

 

Generators do not have tires but still carry the same maintenance
responsibilities as a vehicle, & typically do not get cared for like a
vehicle that you climb into & trust your life with. My 0.02 experience is
that as long as they are operating all is good & get cared for mostly when a
crisis occurs. What I like to call "recycled ignorance."

Hello Mick,

Here is what I'd do:

Check compression on each cylinder, look for psi of about 90(ish).  Also verify 
they are about the same (within a couple of percent).  If its way out of this 
range, stop here.

If they think they've gotten at least 5000 run hours, I'd stop here.  These air 
cooled machines can last longer if well taken care of, but that is the design 
life.  I have a few Kohler air-cooled with >5000 run hours so it can happen.

I'm a fan of checking the integrity of the alternator/rotor with an excitation 
test but you may be limited in what is possible with a cooked controller.  You 
can ask me direct for more details on this.  Probably the controller is cooked 
and that's it, but I have had lightning to more things to generators.

I would try the parts for techs but here in Colorado you can also call Power 
systems West in Aurora.  They will need make, model, serial number and they can 
price out the part for you.  This will at least get you a best case price for 
replacing the controller.  You can't rely on interchangeability of these 
controllers.  There are often changes that need harness modifications.  

Good luck

Re: [RE-wrenches] 2007 Kohler: Wrenches, can you help with parts or smarts?

[Mac Lewis via RE-wrenches]

Hello Mick,

Here is what I'd do:

Check compression on each cylinder, look for psi of about 90(ish).  Also
verify they are about the same (within a couple of percent).  If its way
out of this range, stop here.

If they think they've gotten at least 5000 run hours, I'd stop here.  These
air cooled machines can last longer if well taken care of, but that is the
design life.  I have a few Kohler air-cooled with >5000 run hours so it can
happen.

I'm a fan of checking the integrity of the alternator/rotor with an
excitation test but you may be limited in what is possible with a cooked
controller.  You can ask me direct for more details on this.  Probably the
controller is cooked and that's it, but I have had lightning to more things
to generators.

I would try the parts for techs but here in Colorado you can also call
Power systems West in Aurora.  They will need make, model, serial number
and they can price out the part for you.  This will at least get you a best
case price for replacing the controller.  You can't rely on
interchangeability of these controllers.  There are often changes that need
harness modifications.

Good luck
